WHAT IS NITROUS OXIDE? Nitrous Oxide is a cryogenic gas composed of nitrogen and oxygen molecules. It is stored as a “gas over a liquid” which means that both liquid and gaseous nitrous oxide is delivered into your engine. It is 36% oxygen by weight, which is what produces the added horsepower. By injecting more oxygen (and a corresponding fuel signal), we create the additional power much like a supercharger or a turbocharger does. Nitrous Oxide is considered an “oxidizer” and not a fuel.

2.0 Nitrous System Installation 2.1 Nitrous Bottle Installation The nitrous oxide storage cylinder is typically called a “nitrous bottle”. It is an aluminum cylinder, designed and manufactured to withstand very high pressures. The valve on top of the bottle is a high-flow design that allows easy opening and closing which controls the nitrous flow to the engine compartment. Accurate calibration of your nitrous system depends on the bottle remaining at a stable temperature. In vehicles (such as Co

2.2 Bottle Orientation Accurate calibration of your nitrous system depends on the bottle remaining at a stable temperature. Choosing the proper location and orientation for your bottle can greatly affect the overall operation of the nitrous system. Please read the entire bottle mounting instruction section before making your final bottle location decisions. Bottle placement is critical to the performance of your nitrous system. It is important to understand how the bottle valve and siphon tube a

2.3 Nitrous Bottle Installation After you have determined the location and orientation of the nitrous bottle, use the following procedure to install the bottle: 2.3.1 Street Car Installations 1. Disconnect vehicle’s battery. 2. Determine the location of the bottle within the confines of the rear of the vehicle. 3. Once a mounting location has been determined, raise the vehicle (following all safety practices involved in working on a vehicle from under the vehicle) and verify that there are no fu

2.4 Nitrous Feed Line Mounting 1. Determine the route your main nitrous feed line will follow. Ensure the path does not route the nitrous feed line too close to the exhaust system, suspension, electrical lines/components or tires. 2. Attach nitrous supply line to bottle. 3. Feed nitrous line along proposed route. 4. Secure nitrous supply line to underside of vehicle. Note: Stainless steel covering of the main nitrous feed line is very abrasive. Shield painted components or sensitive system comp

Shown above is a typical EFI solenoid assembly using an unmodified EFI solenoid bracket as well as an exploded view of the nitrous solenoid assembly. Modifications performed to a solenoid bracket depend on many factors. When mounting the solenoid assembly on a vehicle, considerations should be taken regarding any potential interference with the vehicle’s systems or components. The line length between the Performer RPM EFI solenoid assembly and the jet fitting on the nitrous spray nozzle is 24 in

2.7 Fuel Pressure Safety Switch Installation 1. Locate the fuel rail test port fitting. 2. Make sure the vehicle’s engine is cool. Release pressure in the fuel system by pressing down on the valve in the center of the fitting. Cover top fitting with a rag whicle releasing pressure. This will allow the pressure to escape as well as some fuel. 3. After relieving all pressure, remove test port fitting core and install the 1/16 NPT male X 1/8 NPT female brass fitting in its place, using liquid teflo

2.9 Fuel Pump Installation (Continuation) 5. Measure and cut a length of the supplied fuel hose from the outlet of the fuel pump to the fuel hose that runs towards the engine compartment. Connect one end of the cut fuel hose to the barb fitting on the outlet side of the fuel pump and secure with one of the supplied hose clamps. 6. Install the male Ford Fuel Hose Adapter into the remaining end of the fuel hose and secure with one of the supplied hose clamps. Connect the male Ford Fuel Hose Adapte

3.3 Nitrous Electrical System Installation Procedures Determine the location of the relay and fuse holder wire harness. Most common installations locate these components inside the driver’s compartment and close to the fuse panel under the dash. You can also mount the relay and fuse holder harness close to the battery. However, these connectors are water-resistant not waterproof, so care is required when mounting this assembly under the hood of your vehicle. Wire Schematic Origin and Destination

3.5 Arming Switch and Installation The arming switch is a red, lighted switch that is a “MASTER” arming switch for your nitrous system. Without it, your nitrous system would be “on” all of the time and capable of engaging anytime you go to wide-open throttle conditions with your vehicle. The switch, when in the “armed” position, is well lit. Therefore, it should be placed in an obvious position well within the line of sight and easy reach of the driver. Please refer to the procedures below for t

3.6 Microswitch Installation and Wiring (continuation)... The bolts used to attach the microswitch have extra length to allow for spacing the microswitch away from the bracket to offer a level of adjustability of the microswitch. After determining the position of the microswitch, we recommend trimming the bolts for a clean installation. Due to the wide variety of throttle linkage combinations in use, it is impossible to supply a microswitch bracket custom-tailored to each application. The univer
